I would also put Stevenson, Kos, Burkman, Marquardt, Swick, Okami, and Rashad in the top 10 in there weights but it could be questionable.

But people in the UFC that I consider A class fighters are Sherk, GSP, Hughes, Penn, Anderson, Rich, Chuck, Rampage, Mirko, Randy, and Werdum. Franca, Diego, Karo, Tito, AA, and Tim would be borderline.
